DS1818-10 Equivalent & Substitute Parts

Part Overview

The DS1818-10 is a supervisor integrated circuit from Analog Devices Inc./Maxim Integrated's EconoReset series, designed for power management applications. This component monitors a single voltage channel and provides active-low reset output through an open-drain or open-collector configuration. The DS1818-10 is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production requirements. Substitute parts must maintain identical electrical characteristics and mechanical compatibility to ensure direct replacement capability.

REACH unaffected status

Substitute parts are grouped into three categories based on their relationship to the main part:

Direct Manufacturer Equivalents: DS1818-10+ and DS1818-10+T&R differ only in packaging format (bulk versus cut tape) while maintaining identical electrical specifications and active product status.

Parametric Equivalent: DS1816-10+ shares all critical electrical parameters and mechanical compatibility with the DS1818-10, representing an alternative from the same manufacturer series.

Cross-Manufacturer Equivalent: MCP130-300DI/TO from Microchip Technology meets all core electrical and mechanical requirements, with minor variations in reset timeout (150ms minimum versus 100ms minimum).

Engineering Selection Recommendations

For New Designs and Active Production:

DS1818-10+ and DS1818-10+T&R are the primary substitutes for the obsolete DS1818-10. Both parts maintain identical electrical specifications and are classified as active products with ROHS3 compliance. The selection between these two depends on packaging requirements: DS1818-10+ is supplied in bulk packaging, while DS1818-10+T&R is supplied in cut tape format with formed leads. Both are suitable for direct replacement in existing circuit designs.

Alternative from Same Manufacturer Series:

DS1816-10+ provides parametric equivalence within the Analog Devices EconoReset series. This part maintains all critical electrical parameters and mechanical compatibility while offering active product status and ROHS3 compliance.

Cross-Manufacturer Alternative:

MCP130-300DI/TO from Microchip Technology is functionally equivalent with one specification variance: the reset timeout is 150ms minimum compared to 100ms minimum for the DS1818 series. This part is suitable for applications where the extended reset timeout does not conflict with system timing requirements. MCP130-300DI/TO is active and ROHS3 compliant.

Compliance Considerations:

The original DS1818-10 is RoHS non-compliant. All substitute parts listed are ROHS3 compliant, meeting current regulatory requirements for new production and design implementations. All parts maintain REACH unaffected status and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can DS1818-10+ directly replace DS1818-10 in existing designs?

A: Yes. DS1818-10+ maintains identical electrical specifications, including voltage threshold, reset timeout, output configuration, and operating temperature range. The primary difference is product status (active versus obsolete) and packaging format. No circuit modifications are required.

Q: What is the difference between DS1818-10+ and DS1818-10+T&R?

A: Both parts are electrically identical. DS1818-10+ is supplied in bulk packaging, while DS1818-10+T&R is supplied in cut tape format with formed leads. Selection depends on assembly process requirements and component handling procedures.

Q: Is DS1816-10+ a suitable substitute?

A: Yes. DS1816-10+ is parametrically equivalent to DS1818-10, sharing all critical electrical parameters and mechanical compatibility. It represents an alternative within the same manufacturer's EconoReset series and is actively produced with ROHS3 compliance.

Q: Can MCP130-300DI/TO replace DS1818-10?

A: MCP130-300DI/TO is functionally equivalent with one specification difference: reset timeout is 150ms minimum versus 100ms minimum. This part is suitable for applications where the extended reset timeout does not create timing conflicts. Electrical parameters, output configuration, and mechanical compatibility are equivalent.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (DS1818-10+, DS1818-10+T&R, DS1816-10+, and MCP130-300DI/TO) are ROHS3 compliant. The original DS1818-10 is RoHS non-compliant, making substitution necessary for new production meeting current regulatory standards.

Q: Do all parts use the same TO-92-3 package?

A: Yes. All parts listed use the TO-92-3 package configuration (TO-226-3, TO-92-3 / TO-226AA). This ensures mechanical and pin compatibility for direct board-level replacement. DS1818-10+T&R includes formed leads as a packaging option.

Q: What is the voltage threshold tolerance for these parts?

A: The voltage threshold is specified as 2.88V for DS1818-10, DS1818-10+, DS1818-10+T&R, and DS1816-10+. MCP130-300DI/TO has a voltage threshold of 2.925V. Specific tolerance ranges are determined by individual manufacturer datasheets.
